The present invention relates to improvements in livestock dusting apparatus and more particularly to an apparatus wherein the dust container is associated with a weight actuated bellows whereby the weight of the livestock can be employed for supplying air to the dust container and forcing dust from the container against the body of the animal.

An object of the present invention resides in the provision of a livestock dusting container having sprayer outlets associated therewith, a weight actuated bellows being in communication with the interior of the dust container whereby compression of the bellows efiects agitation of the dust within the container and dispensing of the agitated dust from the container against the animal.

Another object of the present invention resides in the novel construction within the dust container wherein an elogated tube is provided for pivotal adjustment relative to the outlet tube whereby the concentration of dispensed dust and air can be preadjusted.

A further object of the present invention resides in the provision of a double check valve whereby depression of the weight actuated valves effects dispensing of dust laden air from the container and expansion of the bellows effects suction of atmospheric air into the bellows for a repeat operation.

A further object of the present invention resides in the provision of an elongated tube having a funnel-like lower end adapted to overlie the inlet connection whereby injection of air from the inlet connection into the funnel-like end of the elongated tube will effect agitation and circulation of the dust within the container for dispensing dust laden air through the sprayer outlet against an animal.

Various other objects and advantages will become apparent from the detailed description to follow. The best form in which I have contemplated applying my invention is clearly illustrated in the accompanying drawings, where- Figure 1 is a perspective view showing the apparatus of the present invention associated with a fence at the gate thereof whereby the animal passing through the gate actuates the bellows for effecting spraying of dust over the animals body;

Figure 2 is a side elevational view of the dust container showing associated therewith a weight actuated bellows disposed in a hole in the ground at the gateway;

Figure 3 is a vertical transverse sectional view taken substantially along the plane of line 3-3 of Figure 6;

Figure 4 is a view similar to Figure 3 but wherein the agitating tube is shown in adjusted relation to the outlet tube;

Figure 5 is an enlarged detail view of a means for supporting the elongated agitated tube;

Figure 6 is a horizontal section View taken substantially along the plane of line fi-6 of Figure 3; and,

Figure 7 is a detailed vertical sectional view taken substantialy along the plane of line 'l---! of Figure 3.

Referring more particularly to the drawings, wherein like numerals designate like parts throughout, [the numeral Ill designates generally the dust container having an inlet assembly l2 at the lower end thereof and the numeral l4 designates generally the weight actuated bellows connected to the inlet assembly l2 by the conduit H5.

The dust container is is best shown in Figures 3 and 4 as comprising an elongated cylindrical tank 18 having a removable closure 20 associated with its upper end and locked thereon by means of the hook portions 22 and pins 24. The tank it; has a longitudinal outlet tube 26 secured to the inner surface thereof and having an open upper end at 28 in communication with the interior of the tank 58. The tank It and outlet tube 26 are formed with apertures in which are disposed the sprayer outlets 3t and 32.

The bottom wall 34 of the tank I8 is formed with an opening at 36 whereby the inlet means I? can be disposed therethrough. The inlet means 12 is comprised of an elongated tubular casing 38 externally threaded at 353 for disposition within the opening 36 of the bottom wall 34. A pair of nuts 452 and 44 are 'threadably engaged on the casing 38 for locking the same relative to the bottom wall 34.

The casing 38 is provided with a closure plug as at its bottom end with a plurality of apertures 48 formed immediately above the closure plug 46. The casing 38 is also provided with a pair of apertured valve seats 5! and 52 upon which ball check valves 5t and 55 are adapted to respectively seat. Ball retaining elements 58 are secured to the inner surface of the casing 38 above the ball checked valve 54 for limiting the upward movement of the valve 5 A tube til is communicated with the chamber 62 between the seats 56 and 52 and is adapted to have the conduit it secured thereto as shown best in Figure 2. i

The upper end of the casing 38 is of reduced diameter at [54. A supporting bracket 66 has its lower ends 68 and 26 secured to opposite sides of the casing 38 while its upper ends '52 and Hi have pins 16 extending therethrough for pivotally supporting the elongated tube l8. The form of the bracket 66 is best shown in Figures 5 and 7 as being of U-shape with a split formed therein whereby the support portions l2 and M for the tube 18 are provided.

The elongated tube has its lower end of funnel-like form at 8% adapted to overlay the reduced diameter outlet 5 of the casing 33. Figure 4 shows the elongated tube is in adjusted relation to the longitudinal tube 25 whereby the concentration of dust in the air dispensed can be controlled.

The weight actuated bellows M is best disclosed in Figure 2 is comprising a base 82 and a top 84 telescopically engaged with the base {52 by means of the telescoping cylindrical walls 8*; 3%. The interior of the bellows as is communicated with the conduit iii and springs 32 normally upwardly urge the top 8 2.

igure 1 shows the dust container it carried by the fence post T adjacent to the gate G whereby when the animal steps on the top 84 of the bellows, air will be forced through the reduced diameter Outlet 65 into the funnel-like end 80 from the elongated tube 18.

into the funnel-like end 5% of the elongated tube '58, the tube will be in preadjusted relation to the outlet tube 25, as shown in Figure 4. Thus, dust within the container it will circulate through the tube '65 by injection as a result of the high speed air passing from the reduced diameter outlet into the funnel-like end 86}. Part of the dust-laden air will pass to the outlet tube 25 and sprayer oulets 3t and 32 to the animals body. As the animal steps off the top of the bellows, the check valve 5 will become seated against the seat 5Q while the check valve will unseat and as a result of the suction permit air to pass from the atmosphere through the apertures it into the conduit it to the bellows for repeat operation.
